I am looking for a non-toxic, earthworm-friendly weed killer for use on a large gravel driveway. Is there anything like this available or something I can make?

A flame weeder is a good choice for killing weeds on gravel or stone block areas. Economical types are sold online and at better garden centers. They look like a cane with a small quart-sized propane cylinder attached to the short end of the cane. There is an igniter on the bottom end. Use this to burn the crowns of the weeds in the driveway.
Another alternative is to use white vinegar in a clean spray bottle to spray on the weeds. Several applications might be needed to completely kill the weeds.
